With the new drop system, your drop timer starts counting once you accept your newest drop. So let's say you get a drop every 40 minutes. Once you confirm your newest drop, that timer starts. You can't just leave the game on and come back to a bunch of new items. One at a time.

What you could do is gather us a bunch of metal and then go scrapbanking for weapons. You trade one scrap for two weapons, and thus 1 refined is 18 items, and so on. Scrap.tf has bots that bank weapons for metal, or you could just go hit up a few trading servers buying weapons.

And then there is the Steam Market. Vintages, Stranges and Killstreak weapons for not that much money (depending on what it is. A Strange Flamethrower is about a quarter, but a Strange Original is nearly $15). Vintage Weapons are usually a few cents and you can get a few by selling Steam trading cards from other games.

steam market is much better than the mann co store if you wanna buy them... I needed a crit a cola and the strange variant was only 11 cents... if I went to mann co it was 50 cents for the regular one.
